To all whom it may concern.'

Be is known that I, vEDWARD CARR, a

- citizen of the United States, residing v at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Bails, of which the following is a specilication, ref- A erence being had to the accompanying drawhereof, which drawings illustrate an 'ema y bodiment of this invention, and on which drawings the same reference characters are used to designate the same parts wherever Y they may appear in each of the several views. Figure 1 is an elevation of a'bail connected with a receptacle; Fig. 2 is a plan view of the bail shown by Fig. 1; and Figs, 3, 4 and 5 are elevations of details of construction ot the bail illustrated by the drawings.

The object of the invention is to provide a bail which can be readily attached to or detached from a receptacle and which. while attached to a receptacle, will be a rigid bail which cannot be detached except when purposely manipulated for that purpose.

Referring to the drawings, the reference i numerals lnand 2 designate bail arms which are pivotally connected by a pivot 3. Each bail arm is bent approximately at right angles as clearly shown by Fig. 1 of the `drawings to extend up from a receptacle and over the top thereof. Slings 4 and 5, which are pivotally connected by a pivot 6, are pivoted to the bail arms by pivots 7 and, 8. A lock 9 is provided to lock the bail arms in one or more rigid positions to make a rigid bail which cannot be detached from a receptacle except when purposely so manipulated. The lock 9 can be made in several different ways but the specie construction illustrated by the drawings is exceedingly simple and consists of a bar which is pivoted to one sling by a pivot 10 and which is provided with a hole k11 which is a little larger than a pin or bolt 12 which passes through the hole and is secured to the other sling. The lower ends of the bail arms may be formed in any suitable manner to engage with a receptacle.

'as below such va line.

Thev bail illustrated by thel drawings is constructed from strap metalas a matter of convenience in manufacturing the same and each sling is illustrated as composed ol a pair of parallel straps, while each bail arm is illustrated as composed of a single strap bent to form a loop 13 and the parallel sides are stiffened and strengthened by spacing members 14 and fastenings 15. The receptacle .16 is illustrated asprovided with pintles 17 and 18 to engage'inthe loops 13, but the invention is notlimited to the specific details of construction illustrated bythe drawings. A latch 19, which is illustrated as provided with a handle 20, is pivoted to a bail arm by a pivot 21 and is adapted to engage with the receptacle 16 to prevent relative movement between the bail and the receptacle except when the latch is purposely actuated.

In order that the invention may be readily understood, the pivot 3 is shown in full lines by Fig. 1 of the drawings as above a line which may be assumed as drawnstraight across from the pivot 7 to the pivot 8, and the pivot 3 is shown by dotted lines Any weight sup ported from the lower ends of the slings 4and 5 tends to swing the lower ends of the slings together but the lower ends of the slings cannot movey toward each other on account of the pin 12 engaging against the inner side of the hole 11 in the lock 9 as clearly shown by Fig. 5 of the drawings. When a receptacle is supported by the bail arms, the weight of the receptacle tends to swing the bail arms upon the pivots 7 and 8 to elevate the pivot 3 but such movement is prevented by the lock 9. `To detach the bail from a receptacle the pivot 3 can be" depressed to the position shown by the dotted lines in Fig. .1 of the'drawings. The hole 11 permits suflicient outward movement 'of the pin 12 that the lower ends of the Vslings can move apart far enough to permit the pivot 3 to be moved from one position to another, as will be clearly understood. The construction is in principle that of rigid triangle, the parts of which cannot be distorted except by changing the position of the pivot 3.

The construction which includes' a lock 'or locks for the purposes stated is the conthe bail arms are prevented from move-Ll` pull will detach the bail from a Ciseness o''action which is ofV great ad-VVK vantage in handling standard' equipment of receptacles as possible lost or waste moveA ments on the part of operators are elimi-V nated, but the lool; can beomitted and the bail arms allowed yto hang from slings without any positive look. Thesbail arms and slings, under the inuenoe oi gravity, will retain substantiallythe positionsshown by Fig. lof the drawings and one or both bail arms finay be eonnterweighted as shown by Fig. L1k of the drawings to regulate the positions which the bail ar'rns will assume Vunder the inflnence of gravity alone.

The great advantage of the bail fis that the hoi-st QBm'a'y pull in any direction for hoisting or moving reeeptacle and no such receptacle. l/Vhat is lolaimedis;Y 1.
